There seems to be a lot of confusion over what hand application method works best or is the safest (straight lines vs. circular motions). The major difference between applying products in a circular motion verse straight lines is your coverage. I feel a circular motion allows you to work in a product more evenly and hit areas at multiple angles for a more thorough application. This is especially important when polishing for best results. The same thing applies for a wax or sealant that you want to be applied to every microscopic peak and valley in the clear coat. The Porter Cable 7424 moves in an oscillating pattern which is basically a tight circular motion meant to replicate circular hand movements. This results in very good product breakdown and coverage for a thorough application.
Some people feel that a circular motion will create micro-scratches in a circular pattern in the clear coat. Therefore with that logic, they feel straight hand motions will only create straight micro-scratches that are less noticeable to an observer. If you are creating micro-scratches in the clear coat your problem lies in your prep work or products and tools used during the process, not your technique. If micro-scratches are being added you may be experiencing one or more of the following problems:
– You are using a contaminated applicator pad
– You are using a non-paint safe applicator pad
– You are using a contaminated removal towel
– You are using a non-paint safe towel
– You are applying a product over a contaminated area
With any one of the above situations you can easily be grinding in contaminates in to the clear coat which can cause micro-scratches regardless of your technique. Additionally the same concept is true if the applicator or removal towel you are using is too coarse. Some common problems we see are people using an applicator pad or removal towel that has old and dry product (i.e. wax) in it or a large piece of contamination that’s abrasive. Contaminates and old product can become lodged in an otherwise good applicator or removal towel and make it a potentially dangerous tool. Contaminates left on the surface of your vehicle can also be very dangerous. To decrease the risk of grinding in contaminates make sure you do a thorough wash with a pre-wash degreaser and use a clay bar to deep clean the micro-ridges of the clear coat. When wiping an area that has contamination you may loosen the contamination or part of it. These contaminates can then be grinded in to the clear coat or become lodged in your applicator or removal towel. It’s very important to regularly inspect all of your towels, applicators, buffer pads, etc. for contamination that could be potentially dangerous and replace as needed.
While each buffer is different I’ll point out some common differences between the Porter Cable 7424 and some of the “generic orbital buffers”. Some of these differences are subtle, but noticeable if you really want the best results. I’ll highlight some of the main differences and why they are important.
One of the best things about a Porter Cable buffer is you can attach a velcro backing plate to it. The velcro backing plate allows you to use various pads, such as the Lake Country foam pads. Changing pads takes only takes a few seconds. The Lake Country Pads are clear coat safe designed to complete each step of the detailing process with maximum results. If you want to remove swirls and imperfections you can use a more aggressive pads or if you want to apply a wax there are nice soft pads, etc. These pads are particularly important for polishing to attain maximum results.
Generic buffers typically use terry cloth bonnets that have several downsides. Some terry cloth is manufactured too firm and can potentially mar the paint. While doing the detail you most likely wouldn’t notice these micro scratches because if you are applying a wax, the wax is covering it up. However after detailing for years I’ve come to notice that some terry cloths can really harm the finish, especially as the bonnet becomes contaminated and worn down. Terry cloth is also very thin which means it can’t absorb contaminates that separate from clear coat while buffing as well as foam pads. These contaminates can grind into the clear coat, where as foam pads are better designed to absorb contaminates into its 1.25 inch thick pad. These pads are very durable so you can clean them and use them over and over again. Some generic buffers have a jerky orbital motion and far less OPMs (Orbits Per Minute), which is essential for effective polishing. The Porter Cable 7424 has a speed dial that allows you to change the power from 1 – 6 or from 2,500 to 6,000 OPM, while many competing buffers just have 1 or 2 speeds. Polishing is the step where you remove swirls, oxidation and really brighten the clear coat for maximum shine. The 3.7 amp motor is very powerful and does a great job of building consistent heat and pressure. Despite this powerful buffer it’s also very safe and has minimal risk of harming your paint. Many traditional orbital buffers require you to have two hands on it, which makes it very difficult to buff very low panels, corners, center of the roof and hood. The Porter Cable’s smooth motion and light weight (7lbs) make it very easy to maneuver around corners and near trim with one hand or two.
One of my favorite parts about the Porter Cable 7424 is its reliability because I really feel like you get what you pay for and it’s backed with a one year warranty. This is a super durable machine that you will be detailing with for years to come.
Selecting the right color paint for a new vehicle or knowing more about your current color will help you understand your paint better. Darker colored paints will typically absorb more light and heat which gives off a deeper reflection then lighter colored paints. The depth and gloss of your paint is a major asset to achieving the maximum shine. Therefore when you complete a full detail on darker colored paint it will generally look better to most people. Conversely black paint also tends to show imperfections such as swirls and contamination build-ups much more than lighter colors. Some vehicles have flat paint while others have metallic flake added to the paint. The metallic flake makes the paint appear to have varying depth. In my opinion the metallic flake takes away from the overall depth and gloss but it helps hide imperfections.
Flat black paint will typically give off the most gloss while metallic silver paint will hide imperfections the most. There is no one universal best color, only the color that works best for you. I recommend darker colored paints to those who enjoy caring for their paint and having that deep shine after a detail. Lighter colors are probably better for those who prefer low maintenance vehicles.

Worn out and contaminated pads can hinder your results as well as potentially add imperfections to your paint. It is good practice to clean your buffer pads every few panels or simply replace them with a fresh pad for maximum results. Allowing the product to cake up will bog down your pad and minimize cutting ability if you are trying to remove imperfections. Periodically cleaning your pads or swapping them out also means that the pads are easier to clean and you will extend the life of your pads. Take advantage of this monthly sale and save today!
To ensure you don’t get any product on areas you don’t mean to you should tape off areas like the door handles, lights, trim, glass, emblems, grills, mirrors, bumpers, rubber seals, etc. We recommend taping off areas that can easily be stained and are hard to avoid. We use painter’s tape (usually 3M’s blue painters tape) that can be found at a local hardware store and it applies and removes very easy from the clear coat.
Using the Porter Cable 7424 around trim and tight spaces takes time to master and you should only do what you feel comfortable with. If you feel a buffer may be dangerous to use around certain areas you should probably avoid using the buffer there. Areas you should be careful around are: trim, emblems, door handles, side view mirrors, windows, sunroof, grills, bumpers, spoilers, joints, lights, etc. Some of these areas may need to be completed with precision hand application. I typically use the Porter Cable 7424 on any area that I can easily buff without risking harm to the surrounding paint, trim, etc. If you feel comfortable holding the buffer at odd angles you may be able to detail more challenging areas like the bumpers, around trim, side view mirrors, etc. It’s okay to hold the buffer at angles as long as you don’t put too much pressure on the part of the pad touching the clear coat. Additionally, not using the supplied side handle for the PC may help you get into some tough to reach places like under the side view mirrors. For those tough to reach areas you may need to move the buffer at a very slow pace and lower the speed to gain more control. When in doubt, side with caution and don’t risk harming the vehicle.
To get a basic understanding on how to properly polish with your buffer, please refer to our Auto Detailing Guide. The Detailing Guide will give you step by step instructions for using the Porter Cable 7424 with polishes, glazes and sealants as well as other valuable insight.
If you don’t feel comfortable using the buffer on your vehicle you may want to test the buffer on a spare panel (junkyards have plenty) or on a vehicle that someone doesn’t mind being a test subject. Start with the speed very low and move slow and steady to allow yourself to master the way the buffer operates. We recommend the first time you use the PC 7424 you apply a glaze, sealant or wax. These kinds of products are very easy to apply and help you get used to the orbiting motion of the buffer. After you feel comfortable with the buffer you can then move on to using polishes, which utilizes the same skill set. Polishes require more heat and pressure to be properly worked in to the clear coat for the best results. The biggest difference when using a polish is that you’ll operate the Porter Cable 7424 at a higher speed, move the buffer slower, make significantly more passes and use more pressure.
You may also want to pick up some blue painter’s tape and protect any trim or other areas the buffer may accidentally hit during the course of normal usage. This will save you time and aggravation trying to restore discolored trim.
Go slow and take your time. You will achieve the results you are looking for with more and more experience.

Rotary buffers and orbital buffers, like the Porter Cable 7424, are both great tools and essential to any detailing professional or enthusiast. Applying a polish is the primary reason detailers turn to using a buffer. Most polishes contain cutting particles (or abrasives) designed to remove an ultra fine layer of clear coat. Polishes remove fine scratches, swirls, oxidation, water and other common surface imperfections. Imperfections in the clear coat cause light to fragment which creates a dull shine. Removing these imperfections allows light to pass more directly through the clear coat, thus giving you a deeper reflection and brighter reflection. Polishing your paint is generally the step that can produce the most dramatic improvement in the overall finish of your paint.
Both orbital and rotary buffers are typically used with a velcro backing plate that adheres to foam pads with velcro backings. The foam pads are available with varying textures designed to help you achieve different levels of pressure and heat. The denser the pad, the more cutting ability it will have. More porous pads are softer and designed for applying sealants and waxes. It is important to match the appropriate pad to the product you are using.
The horror stories about rotary buffers can be true because rotary buffers are difficult to use for beginners. With the proper training and experience the rotary buffer can be an extremely effective tool. Rotary buffers spin continuously in one direction at very high speeds and generate a tremendous amount heat. This allows the buffer to polish out deep imperfections enabling you to restore the clear coat to like new condition. This power is what also makes the rotary buffer dangerous in the hands of those without experience. If you leave a rotary buffer on the same part of your paint it can burn the paint in just seconds. Also, on areas that have a lip, like the trunk lid, it is easy to have the edge of the pad nick the top of the rear bumper to leave you with a burn mark. Rotary buffers are so powerful that I only recommend them for applying polishes. Using a rotary buffer is generally more tiring because it requires more effort and it’s slightly heavier than a typical orbital buffer. You must hold this buffer with two hands at all times.
Orbital buffers move in a random orbit which is designed to replicate a hand buffing motion. This oscillating motion generates far less heat and is very clear coat safe. Even with the strongest polish and pad combinations detailers have a difficult time damaging the paint beyond repair when using the Porter Cable 7424. The Porter Cable 7424 is one of the highest quality orbital buffers available to detailers. It has quickly become the favorite tool of many weekend detailers and professionals alike. A quality random orbital buffers like the Porter Cable 7424 can produce up to 6,000 orbits per minute (OPM’s). The Porter Cable 7424 is powerful enough to break down polishes effectively, but not risk damaging the paint. This pressure is important because it helps work polishes in to the clear coat to effectively remove swirls, fine scratches, oxidation and other light imperfections. You should be able to remove the majority of light scratches and surface imperfections with this buffer. Orbital buffers are great for applying polishes, glazes, sealants and waxes. The Porter Cable 7424 can be used with two hands or one and has an available side handle.
Both tools are great but it’s important to use the one that best fits your needs. The rotary buffer is a great option for anyone who is willing to take the time to practice and refine their skills. If you truly want to remove all or most of the surface imperfections in your paint then this may be the buffer for you. If you are pursuing a profession in detailing this is a great tool to know how to use that will help differentiate your business. If you prefer a tool this is still very effective and user friendly an orbital buffer may better fit your needs. If you want to avoid unnecessary risks or if you’re looking for an all purpose buffer I recommend the versatile Porter Cable 7424 orbital buffer.
